Sources of Industrial Projects for DFMA Course
Jon E. Freckleton Rochester Institute of Technology
It has been our experience in both the Capstone Senior Design course and the Design for Manufacturing and Assembly (DFMA) course that students are far more interested in working on “real” projects. The problem is finding industrial support for about 100 projects per year. This paper will consider the various sources we have used. RIT works on the quarter system; DFMA is a four credit hour course; the project represents 25%-40% of the grade.
Background The undergraduate DFMA course started as a required course 10 years ago. It was based on a very successful graduate course. The graduate course was an evening course with almost all students holding full-time engineering jobs (‘) . Projects usually related to the students job or were obtained from a peer at work. The few full time students were allowed to use a commercial product they had at home or purchased at a local store.
RIT is a quarter based institution with a cooperative education program. For engineering students it is a five year program. As freshman and sophomores, they attend three consecutive quarters with the summer quarter as vacation. As third, fourth, and fifth year students they alternate academic quarters and work blocks. They must complete five co-op work blocks to graduate. The students are split into “A” and “B” blocks so the Institute holds classes all four quarters and about 50% of each class is on campus each quarter. Some co-op employers hire only for double blocks, wanting the student for six consecutive months.
DFMA is a required course for fourth year students. Prerequisites are Geometric Dimensioning and Tolerances and Manufacturing Processes. A normal track student will have completed two work blocks prior to taking this course. Due to a significant number of transfer students, and students who have experienced academic problems, the class usually has a few third year students, and several fifth year students.
The course covers two major areas: Design for Assembly (DFA) and Design for Manufacture (DFM). DFA covers two quantifiable measurements of assembleability; Boothroyd Dewhurst (BDI) manual and software techniques’2’ , and the SEER (3) Technology software technique. DFM covers: casting, molding, sheet metal, powder metal, extrusion, forging, and machining. The BDI DFM software (4) I.S used for the five processes that have been developed to date.
Homework consists of: 1. Reading from the text 2. Four papers 3. A DFA manual calculation 4. A “Tip-a-Can” design, and working prototype”’ 5. A DFMA project; due in phases, to force timely work, and to make sure the grading workload is almost livable.
